Abstract
A method which enhances a disinfection process by using a catalyst which increases in effective surface area during the process. Also disclosed are contact lens disinfecting systems which are designed to maintain a high concentration of hydrogen peroxide solution for a longer period of time before increasing the overall surface area of catalyst exposed to the hydrogen peroxide solution. The devices utilize pressure from expanding oxygen generated within the system through use of a small catalyst, or through exposure of only a small portion of a large catalyst, to control deployment of the large catalyst for completing disproportionation of the hydrogen peroxide.
